G4874–συναναμίγνυμι–sunanamignumi

I wrote to you in that letter that you were not to associate with fornicators;

συναναμίγνυσθαι sunanamignusthai “to associate with”

But what I meant was that you were not to associate with any one bearing the name of "brother," if he was addicted to fornication or avarice or idol-worship or abusive language or hard-drinking or greed of gain. With such a man you ought not even to eat.

συναναμίγνυσθαι, sunanamignusthai “to associate with [him]”

and if any one refuses to obey these our written instructions, mark that man and hold no communication with him--so that he may be made to feel ashamed.

συναναμίγνυσθαι sunanamignusthai “to mix with”
